EnergyStation 1000W Ballast, for Hydroponic HPS MH Grow Light System, Digital Dimmable Electronic Horticulture Ballast, Cali HPS MH Ballast for Indoor Growing, 1000 Watt Ballast for Indoor Growing

This ballast was less expensive and runs way cooler than others I've purchased. In fact, I believe this might be the coolest running ballast I've had so far.

This is one of the better ballasts on the market, runs very cool, the fan seems reliable from use, and the ballast is....curiously cheap? I'm not sure why they sell it at the price point they do for the excellent build quality.The dimmer is great, it's not too loud for the temperature it keeps it at(ice cold), and it's oddly small for what it accomplishes. Other manufacturers should perhaps take note.I can't see anywhere to improve upon this product currently. I am utilizing it in a sheltered outdoor setting for a variety of ornamentals and it hasn't died from mild humidity exposure unlike many. It will support both HPS and metal halide bulbs.

Awesome

works as it is intended to

Perfect! Does not get hot! Great packaging. I have been using it on 100% for over two months. I have other brands as well but bought a second Cali a few weeks ago. Great price and quality.

Coolest running ballast. Ive tried 3 different brands all hot to even touch. But not this one hours running and its still warm. Only been a day so dont know about longevity. Overall nicely built

I use 1000 watt winged metal halides for work and they blow away all 1000 watt led setups.Metal halide is still king of high wattage brightness. Period. Led street lights or grow don't come close in terms of high wattage efficiency. The surface area, drivers and needed heat sink for a 1000w led are not durable and insanely expensive and bulky.For any work light that you rely on for operations, go bright or go home!

Simple but has basic features. Lightest weight ballast I ever owned. Works well so far.
